Is there a limit to the normal amount of time you should be able to hold it?

So I've found myself able to hold my bowels for days at a time. Like I went on a week long canoeing trip with friends and there weren't any bathrooms. I meant to go more often but there were no good times so over the course of a week I went like twice, I don't have any constipation issues (I very much just don't get the urge if I don't think about it) but this doesn't seem normal.

Edit: camping was just one example, I tend to be able to hold it for like two days when at home
